To all whom it may concern:

[lo it known thetl, HENRY D. BARAGWANATII, a citizen of the United States of America. and t t-resident of (.hicago in the county of Cook and State of Illinois, 7

hove invontcd certain new and useful Improvements in -l3a-rometric (.ondensers, of which the followin is s specification.

The main object of this invention is to provide an improved form of cjcctor condenser of the barometric type, having a dry air pump connection for exlmusting ,oir from the condenser at a point below the narrowest point of the throat, thereby largely increasing the efficiency of the condenser with a minimum quantity of water.

Thisobject is accomplished by the device shown in the accompanying drawing which represents :1 vertical.

section, partly broken ztwny, of at barometric condenser constructed according to this invention.

In the construction shown in the drawings the usual vertical steam pipe]. is provided at its upper end with a double elbow 2 so that the steam is discharged in a downward direction. A relief valve 3 is provided at the .uppcrcnd oi the steam pipe l nnd is adjusted to permit the escape of steam. when a certain normal pressure is exceeded. 'lhe elbow 2 discharges into Zl, steam funnel 4 which is mounted in ulincrnent therewith and is vertically adjustable by means of the hand wheel 5 and stem 6 which is threaded into 1. yoke 7 at the upper nd of the funnel 4. A steam and Will/01 mixing funnel 8 is secured in direct a] inemcnt with the steam funnel 4. The upper end. of the funnel 8 is surrounded by a casing l) which connects said funnel with the elbows 2. The condensing water is supplied to the casing 9 by the pipe 10 und'is admitted to the funnel 8 at the inlet 11 around the edges of the steam funnel 4. The treat of the inlet ll is controller] by adjusting the funnel 4 vertically with respect to the funnel 8. An ejector throat 12 is secured to the lower end of the funnel 8 and forms an unbroken continuation thereof. The throat 12 is gradually contracted in transverse area until it reaches a. minimum at a point intermediate of its ends, preferably closer to the lower end than to the upper end and the area is then gradually increased toward the dis charge end as is usual in the throats of injectors and electors. As is well known o tliroot of this shape along which steam and Water are delivered in a longitudinal direction causes the discharge of it much greater quantity or steam or water than would be the case thethroat were not so contracted. The throat 12 is sur- 'rounded by 2'. second casing 13 which communicates at its lower end with o barometric tail pipe .14. The upper end of the till pipe His located 33 feet above the level of the Wztilm in the hot well, so that under no circumstances can the we tor ever ris'e to a sufficient height to submerge the lower end of the throat 2. The internal diameter of the pipe 14 is, throughout its length to the hot well, greater than the internal diameter of the ejector throat l2, so unto permit all \Yztiil passing through the throat l2 to'be freely and rupidly curried down. The casing 13 is connected bylncans of a pipe 15 with u dry air pump which exhausts the air iron: the casing 13 and produces t vacuum below lhc dischargc end 01' the throat l2. 'lhe flange 1.6 at the upper cull of the throat 12 forms the upper end of the casing lit and serves as it closure for preventing communicutionbetween the dry-air pump connection 15 :1 nd the steam and .wuter inlets except through the lower end of said throat.

The operation of the device shown is as followsm fiteztm enters the condenser from the pipe 1 and passes directly downward through the iunncl 4. Water cutering the casing 9 from the pipe 10 is discharged in a thin sheet around the lower edges oi the i' u nnel 4. The steam and water mix in the funnel 8 and pass through the ejector throat 12 at ohigh velocity. The water then passcsinto the barometric tail pipe 14 by which it is carried to the hot Well. flhc l-(til pipe 14 is of coin sidcntbly greater diameter lhan the throat l2, being usually about twice such diameter. The dry air pump exhausts the air which has been carried through the throat 12 by the stezun and Wilil'l. This greatly increases the eii'lciency of the condenser, and permits of the use of a small amount of WttLOl in the tail-pipe l4 and in the hot-well.

What I claim as my invention and desire to secure by Letters Patent is:

1. A barometric condenser comprising n combined stea'm and water mixim, funnel. an elongated gradually -con-' trncted ejector throat below said funnel and forming an unbroken continuation thereof, a casing surrounding the said throat and having a barometric outlet pipe communicating therewith below the discharge end of said throat, and an air outlet communicating with said casing above the discharge end of said throat and adapted to draw the air from saidfnnnelv below the discharge end of said throat.

2. A lncrometric condenser comprlsing :1 combined stezum and water mixing funnel, an elongated gritdually contracted ejector throat below said funnel and forming an unbroken continuation thereof, a casing surrounding the suid throat and llElVlllK fl barometric outlet'pipe connected thereto below the discharge-end of said throat and having A greater internal diameter, throughout its length, than the contracted part of said throat, and an alroutlet communicating with said casing above the discharge end of said throat and adapted to draw the air from said funnel below'the discharge end of said throat.

-.'-l. A barometric condenser comprising a casing having steam and water inlets, an elongated gradually contracted ejector throat mounted in allnement wlth said steam 31nd water inlets. a barometrlc outlet pipe in allnement witln said throat, a dry air pump connection eomznunlcuting with said casing above the dlscharge' end of said throat and adapted to draw air from below the discharge end of sold throat, and a closure preventlng communlcutlou between :mld connection and sold inlets except through the discharge end of said throat.

4. In a condenser, the combination of a case divided into upper and lower chambers nnf baring; steam and un- [er inlet connections opening into the upper chamber and an airrxhausr connection leading out of the upper part, of the lower chamber. a funnel leading from the upper into the lower chaniher. said funnel having its upper end ex tending above the bottom of the upper chamber and havine; its lower part extended to form an. Qltii'lillllfd coir t'racted ejector throat, and .1 harometrlc outlet. pipe leadll out of the lower part of said chamber.

- haroinetric condenser having steam and water in lets, a steam funnel receivlng' steam from the former; an ejector throat adapted to niix and discharge ihe steam and water from said inlets, the upper end of said thro lying close to the lower edge of said funnel. a. haroineti outlet pipe adapted to convey the water dischal throat. and an air outlet. communicating with said hart metric outlet pipe above the discharge end of said throat and adapted to draw air from the discharge end of said throat and exert a suction in said throat in the direction of its discharge.

ti. A lmrmm-lrir condenser comprising an elongated and lo\\"n\\'ar1ll,\' tape-red ejector tulle, a vertically adjustahhy steam-inlet funnel adapted to discharge steam into said ed by said- -ler inlet 1' .i

tube. achamber sorionnding said steam-inlet funnel and the upor part of said ejector tube and having a water inlet, a casing: surrounding the main lower part of said eject tube and having connection at its lower end with a barometric (r charge pipe, and an air-exhaust: connec lion in said lower casing at a point above the lower end of said ejeczur tube.
